1. Genetic variability in Capsicum spp. accessions through multicategorical traits
ABSTRACT Capsicum peppers originate from the American continent. Their culinary and medicinal potential, first exploited by indigenous peoples over 7000 years ago is vast, however more studies are needed. Despite the existence of germplasm banks that house hundreds of accessions of the genus, only a little of this diversity is seen in large markets. In this

2. X-ray Scattering and Chemometrics as Tools to Assist in the Identification of Gunshot Residues by Wavelength Dispersive X-ray Fluorescence Spectrometry
Wavelength dispersion X-ray fluorescence spectrometry (WDXRF) is a non-destructive technique and therefore attractive for gunshot residues (GSR) analysis. It is well known for determination of inorganic constituents of samples. However, X-ray scattering region spectral data is not commonly used, although it may provide information about organic constituents

3. Genetic variability in peppers accessions based on morphological, biochemical and molecular traits
ABSTRACT The evaluation of genetic diversity among the accessions of a germplasm collection results in information about promising materials suitable for breeding programs. Thus, the goal of this work was to characterize Capsicum baccatum accessions from different Brazilian regions, based on morphological, biochemical and molecular traits, aiming to support

4. CHEMICAL VARIABILITY OF Allamanda cathartica L. FLOWERS ASSESSED BY MULTIVARIATE DATA ANALYSIS
The aim of this study was to determine the chemical variability of Allamanda cathartica flowers collected in different localities of Santa Catarina State, Brazil. Extractive solutions (25 samples) were analyzed by HPLC-DAD for the qualitative and quantitative profiles of the iridoid plumieride, the flavonoid rutin as well as total flavonoid content expressed

5. Headspace analysis and characterisation of South African propolis volatile compounds using GCxGC–ToF–MS
ABSTRACT Propolis also known as "bee glue or bee resin" is a resinous mixture of bee saliva or bee wax and exudate from tree trunks and flowers, produced by honeybees. The composition of propolis varies depending on the vegetation the bees can access. It is therefore expected that propolis obtained from various localities may have different chemical profiles

6. Combinations of distance measures and clustering algorithms in pepper germplasm characterization
RESUMO Com o aumento da perda da variabilidade genética e a procura por genótipos mais adaptados e produtivos, a caracterização e a avaliação dos genótipos conservados em um banco de germoplasma são de elevada importância. Essas podem ser obtidas de várias formas, gerando dados quantitativos e qualitativos. A análise conjunta dessas variáveis pod

7. Biopsychosocial characteristics of sex offenders: An analysis of legal proceedings
Resumo Nesta pesquisa, identificaram-se e analisaram-se características biopsicossociais de pessoas acusadas de agressão sexual contra criança/adolescente, entre 2012 e 2014, em três comarcas do estado do Pará. Os dados foram coletados por meio de consulta aos autos de processos jurídicos, e registrados em formulário para caracterização biopsicossoc

8. Phenotypic and molecular characterization of apple (Malus × domestica Borkh) genetic resources in Greece
ABSTRACT: The phenotypic and genetic analysis of apple (Malus × domestica Borkh) genotypes is essential for breeding species. Information on the morphology and genetic structure of apple offers significant help for germplasm maintenance and selection of suitable material to breed superior cultivars. This study shows the results of an investigation on the mo

9. Influence of growth regulators on distribution of trichomes and the production of volatiles in micropropagated plants of Plectranthus ornatus
ABSTRACT The profile of volatile organic compounds, the glandular and non-glandular trichomes of Plectranthus ornatus, obtained by in vitro cultivation, was evaluated in plants grown in Murashide and Skoog medium supplemented with benylaminopurine at 4.5, 9.0, and 18.0 µM + naphthaleneacetic acid at 5.37 µM, kinetin at 4.7, 9.3 and 18.5 µM + naphthaleneac

10. Performance quantification of clustering algorithms for false positive removal in fMRI by ROC curves
Abstract Introduction Functional magnetic resonance imaging (fMRI) is a non-invasive technique that allows the detection of specific cerebral functions in humans based on hemodynamic changes. The contrast changes are about 5%, making visual inspection impossible. Thus, statistic strategies are applied to infer which brain region is engaged in a task. Howeve

11. Pollen morphology and its taxonomic significance in the genus Bomarea Mirb. (Alstroemeriaceae) - II. Subgenus Bomarea
Pollen morphology of 52 species (out of c. 79) of the Bomarea subgenus Bomarea was examined using light microscopy and scanning electron microscopy (SEM), or using SEM alone. The studied species of Bomarea were stenopalynous, characterized by large, oblate, monosulcate monads with reticulate exine sculpture in most species. Wide variation was observed in qua

12. Composición de lianas y bejucos en el Chocó Biogeográfico Colombiano
AbstractIn order to determine the distribution patterns of lianas and vines in the Colombian Chocó biogeographic, we constructed a data base of presence of species of lianas and vines reported to December 2012, from digital databases, records scientific literature and direct inspection of herbarium specimens considering ecosystem types (environments), from
